SCROPH ULARIACEAE 
1. N. tabacum L. Common Tobacco. Leaves half-clasping, ovate, 
oblong, elliptic or lanceolate; calyx-teeth unequal; corolla red, its tube 
white; throat more or less inflated.—Cult.; native of America. The use 
of tobacco was introduced into England by Sir Walter Raleigh. Sir 
Walter started such a smoke as will in all probability never be ex¬ 
tinguished in Christendom. The price of smoking tobacco aside, our 
people pay indirectly (through conflagrations traceable to smoking) a 
larger sum by far for this kind of 
luxury than any other. Tobacco 
has also been made \famous by 
'‘little Johnny Reed,” though not in 
the way that was intended.
